CORTEX A8 on RVDS

Hi,

     I have a query regarding CortexA8 on ARM workbench IDE and RVDS.
When i choose the target as CortexA8 and write a small "helloworld" program it works.
But when i implement a small function and load the image in RVDS, the control comes to the main.
And after pressing F11(stepping in)it goes to the infinite loop instead of coming to the first statement.
so can u please tell where i am going wrong.What should i do to rectify this problem?

    Hi,
              Go to the control tab of the RVDS and change the coprocessor access permissions, Change the access permission of CP10 & Cp11 as "Privilleged and User Mode" i.e.., the value for the variable is 0x00f00000. And also go to the VFP tab and enable the VFP it works. Other wise it will be in infinite loop. For more details of seeting these parameters go to ARM CortexA8 TRM and see the section Coprocessor Access Premission.
